Anyone have experience with pairing the RME ADI-2 DAC with a 009? Good synergy?

Looking at my chain, DAC is definitely the weakest link and I've been eyeing the ADI-2 for a while due to its performance and feature set.
Just by chance, I'm right now using that DAC with my headamp aristaeus and 009....sounds just fine!

So, eBay has a few people in Japan (with 100% feedback) selling the 700a. I’ve been doing research on that model and apparently it is better than the mk2, which people seem to dislike a lot. Does anybody here have the 700a? Apparently it’s meant for the Japanese market. Also, any comparisons with the mk1 and 700a?

It's not better. Afaik 007A is 100% the same as the 007MK2 one has silver housing the other has the black housing, that's pretty much it, same production line, same everything.

The difference is that these headphones have been in production since 2007 and there has been at least two silent revisions which change the sound, the newest version has slightly different earpads as well (one giveaway at least - unless brand new earpads from this new batch were fitted...), the small port near the cable entry, they have started to close down that slightly as well. If one is selling new old stock pieces they might not sound the same as the ones that were produced just now. They started with SZ2 serials, then SZ3, later SZ2 serials have appeared again, so not really possible to trace back the year of manufacturing from the SN.
And of course the system configured heavily affects the sound, in some setups it can sound very unbalanced.

Thanks for the info! :beerchug:

I guess it’s back to searching, or maybe I’ll just take the risk ( they offer free returns) :thinking:

Has anybody noticed that older STAX Amps use an 180 degress phase inversion? Meaning that pin 2 and 3 are switched as compared to the international Studio Standard?

I have the high-amp ALPHA CENTAURY V9.5 hybrid amp now here to compare it with my SIRIUS V9 transistor amp.
I would be interested in your comparison.
I also have the modded T1s with the SR-009 and still considering an amp upgrade, which one do you like the most with the 009?

Can I connect a DAC with PIN 2 = hot and PIN 3 = cold to an older Stax amplifier with PIN 2 = cold and PIN 3 = hot? Should work anyway.
You will get a 180 degree phase inversion, but I'll doubt you'll hear that :wink:
